Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to a vegetable crop greenhouse with external drainage function. Background Technology

[0002] With the continuous development and progress of society and the economy, and the improvement of people's material living standards, off-season vegetable and fruit cultivation is becoming increasingly popular. Traditional agricultural production models can no longer meet the needs of modern civilization. In order to improve planting yield and efficiency, and to make planting not limited by time and location, new agricultural facilities are widely sought after by industry professionals.

[0003] Greenhouses, as a new type of agricultural planting facility, are common field planting tools that control temperature, humidity, and light, allowing crop cultivation to be unrestricted by time, season, or region. They effectively prevent pests and increase crop yield and economic value. Currently used greenhouses are equipped with ventilation screens around their outer perimeter to effectively block pests from entering, ensure air circulation, and flexibly regulate humidity and temperature. In modern greenhouses, to provide crops with the necessary water, help regulate humidity balance, and improve the crop production environment, several sprinklers are installed along the length of some longitudinal tie rods in the greenhouse frame. However, due to the unreasonable distribution of the ventilation screens and transparent film, as well as the unreasonable design of the connection structure between the ventilation screens and transparent film at the joints, large amounts of water often accumulate in the soil near the edges of the greenhouse when the sprinklers spray water onto the crops. This seriously affects the normal growth of crops around the waterlogged areas. Therefore, this paper addresses the above problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a vegetable crop greenhouse with external drainage function. By optimizing the structure of the greenhouse outer mold, the lower edge of the mesh and the upper edge of the plastic skirt film are joined in the pressure groove of the pressure rod fixed on the arched frame according to the external drainage method. The lower edge of the mesh and the upper edge of the plastic skirt film are pressed and fixedly connected by the pressure groove spring adapted in the pressure groove. This effectively guides the water sprayed on the mesh to the outside of the plastic skirt film, solving the problem of excessive water affecting the normal growth of vegetable crops adjacent to the long side of the greenhouse in traditional greenhouses. It ensures the uniformity of water spraying, improves the quality of vegetable crops, and has high application value.

[0005] The technical solution adopted in this utility model is as follows: a vegetable crop greenhouse with external drainage function, including an arched frame. Multiple nozzles connected to water pipes are installed on the longitudinal tie rods of the arched frame along its length. The two long sides of the arched frame are provided with mesh, and a plastic skirt film with its lower edge fixed to the ground is provided below the mesh. The lower edge of the mesh and the upper edge of the plastic skirt film are joined in the membrane groove of the pressing rod fixed on the arched frame according to the external drainage method. The lower edge of the mesh and the upper edge of the plastic skirt film are pressed and fixedly connected by the pressing groove spring adapted to the membrane groove of the pressing rod, so that the water sprayed on the mesh flows downward to the outside of the plastic skirt film. The top of the arched frame is provided with a plastic top film with its lower edge located outside the plastic skirt film when unfolded and the mesh exposed when rolled up.

[0006] The upper edge of the plastic skirt film extends to the upper side wall of the groove opening of the pressing groove rod, and the lower part of the plastic skirt film is attached to and adapted to the lower side wall of the groove opening of the pressing groove rod. The lower edge of the mesh is located outside the upper edge of the plastic skirt film and adapted to the groove of the pressing groove rod. The pressing groove retaining spring adapted to the groove of the pressing groove rod presses and fixes the lower edge of the mesh and the upper edge of the plastic skirt film tightly.

[0007] Furthermore, a drainage ditch is provided on the outer side of the plastic skirt film at the fixed position with the ground.

[0008] Furthermore, the upper edge of the yarn mesh is pressed and fixed by another pressing groove rod and pressing groove retaining spring fixed to the arched frame.

Detailed Implementation

[0017] The following will be based on the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0020] A vegetable greenhouse with external drainage function includes an arched frame 1. Multiple nozzles 3 connected to water pipes are installed along the length of the longitudinal tie rods 2 of the arched frame 1. Two long sides of the arched frame 1 are equipped with mesh screens 4. The mesh screens 4 effectively block pests from entering the greenhouse, provide some shading, facilitate ventilation, and help regulate humidity and temperature. Below the mesh screens 4, a plastic skirt 5 is fixed to the ground at its lower edge. The plastic skirt 5 improves the greenhouse's insulation, prevents pests from entering from below, reduces the accumulation of dust and dirt inside the greenhouse, and facilitates cleaning. The lower edge of the mesh screens 4 and the upper edge of the plastic skirt 5 are aligned with the greenhouse structure. The external drainage method is connected to the membrane groove of the pressing rod 6 fixed on the arched frame 1, and the lower edge of the mesh 4 and the upper edge of the plastic skirt film 5 are pressed and fixedly connected by the pressing groove spring 7 adapted in the membrane groove of the pressing rod 6. This allows the water sprayed on the mesh 4 to flow downward to the outside of the plastic skirt film 5, improving the situation where the water sprayed on the mesh 4 flows directly downward to the soil inside the plastic skirt film 5. This avoids the adverse effects of excessive moisture in the soil inside the plastic skirt film 5 on the normal development of crops, and ensures the quality of vegetables on the two long sides of the greenhouse. The top of the arched frame 1 is provided with a plastic top film 8, which is located outside the plastic skirt film 5 when unfolded and exposes the mesh 4 when rolled up.

[0021] The specific structure for the connection between the lower edge of the mesh 4 and the upper edge of the plastic skirt film 5 according to the external drainage method is as follows: The upper edge of the plastic skirt film 5 extends to the upper side wall of the groove of the pressing rod 6, and the lower part of the plastic skirt film 5 is attached to the lower side wall of the groove of the pressing rod 6 and fits into the film groove. The lower edge of the mesh 4 is located outside the upper edge of the plastic skirt film 5 and fits into the film groove of the pressing rod 6. The pressing groove retaining spring 7, which fits into the film groove of the pressing rod 6, presses and fixes the lower edge of the mesh 4 and the upper edge of the plastic skirt film 5 tightly. Specifically, since the crops in the greenhouse need to be sprayed every day, in order to avoid the water drawn out by the mesh 4 from accumulating outside the greenhouse and forming puddles, a drainage ditch 9 is specially opened on the outside of the fixed position of the plastic skirt film 5 with the ground, so that the water drawn out of the greenhouse is diverted through the drainage ditch 9. This design improves drainage, preventing water accumulation outside the greenhouse and facilitating rainwater runoff. Traditional greenhouses often have an inefficient connection between the mesh screen 4 and the plastic film, causing water sprayed onto the mesh screen 4 to flow down to the inner wall of the plastic film and then along the long side of the greenhouse, creating an area of ​​excess water (greater than 150mm wide). This severely impacts root respiration in the affected area, leading to frequent crop diseases. A redesign optimized the connection between the lower edge of the mesh screen 4 and the upper edge of the plastic skirt film 5, connecting them according to the aforementioned external drainage method. This allows water sprayed onto the mesh screen 4 to flow downwards along the outer wall of the upper edge of the plastic skirt film 5, thus clearing the water from the outside of the plastic skirt film 5. This resolves the adverse effects of the inefficient traditional connection design on some crops inside the greenhouse.

[0022] In the above structure, by optimizing the structure of the outer mold of the greenhouse, the lower edge of the mesh 4 and the upper edge of the plastic skirt film 5 are joined in the film groove of the pressing rod 6 fixed on the arched frame 1 according to the drainage method outside the greenhouse. The lower edge of the mesh 4 and the upper edge of the plastic skirt film 5 are pressed and fixedly connected by the pressing groove spring 7 adapted in the film groove of the pressing rod 6. This effectively guides the water sprayed on the mesh 4 to the outside of the plastic skirt film 5, solving the problem of excessive water affecting the normal growth of vegetable crops adjacent to the long side of the greenhouse in traditional greenhouses, and ensuring the uniformity of water spraying.

[0023] The upper edge of the mesh 4 is pressed and fixed by another pressing groove rod 6 and pressing groove retaining spring 7 fixed to the arched frame 1.

[0024] This technical solution has a simple structure and novel design, achieving the design goal of small improvements with great benefits. It is low in cost, easy and quick to optimize the structure, effectively improves the quality of vegetable crops, and has high application value.
